build file location for sublime version 3
sublimetext3
Solution
`Language.sublime-build` files (and everything else that used to be under the `Packages/Language` hierarchy) are now included in the zipped `Language.sublime-package` files found in `Sublime Text Build 3XXX/Packages/`. I haven't found an obvious way to edit these files in a cross-platform-consistent manner, so the easiest thing is to unzip the `.sublime-package` file into a folder named for that language, then move the folder to the `Sublime Text Build 3XXX/Data/Packages/` folder. As I understand it, any file in `Data/Packages/Language` will overrule whatever is contained in the corresponding `Packages/Language.sublime-package` file.
EDIT
For Windows installations (not unzipped portable installs) use the `C:\Users\YourNameHere\AppData\Roaming\Sublime Text 3\Packages` folder. The `Users` subdirectory in this folder is where all your user-specific preferences, keymaps, build systems, etc. go, similar to the `Packages\User` directory in ST2. So, if you want to unzip and modify the `Python.sublime-package` file, for example, unzip it into `AppData\Roaming\Sublime Text 3\Packages\Python` and you'll be all set, as I described above.
CLARIFICATION
The `Packages` directory is the one opened when selecting `Preferences → Browse Packages…`:
- Linux: `~/.config/sublime-text-3/Packages` or `~/.config/sublime-text/Packages`
- OS X: `~/Library/Application Support/Sublime Text 3/Packages` or `~/Library/Application Support/Sublime Text/Packages`
- Windows Regular Install: `C:\Users\YourUserName\AppData\Roaming\Sublime Text 3\Packages` or `C:\Users\YourUserName\AppData\Roaming\Sublime Text\Packages`
- Windows Portable Install: `InstallationFolder\Sublime Text 3\Data\Packages` `InstallationFolder\Sublime Text\Data\Packages`
The exact path depends on version and whether or not you upgraded from Sublime Text 3.
Also, instead of manually unzipping `.sublime-package` files, just use the excellent `PackageResourceViewer` utility. It does exactly what I described above without the hassle.
Problem
The Sublime2 build files are located at `\Sublime Text2\Packages\` folder, but I cannot figure out where Sublime3 put those files. Can anyone give me some help?
